A nice addition.
You should redo all references of "Mt. Curtis-Gilbert" to "Gilbert Peak" as the latter is the official name (once again).
Also, you should provide a pronunciation for the peak as most people will want to pronounce it similar to Grand Teton. It is pronounced "tie-it-un."

The 1904 Mount Adams USGS map had "Gilbert Peak" and an elevation of 8,201 ft. Curtis-Gilbert was introduced later but I suspect it was never official. And if you note, the words "Gilbert Peak" appear on the (current) map.

And an interesting note about Gilbert's height per an email exchange with Dr. Roper:"Lastly, the benchmark atop Gilbert has 8201 stamped on it. Where did the 8184 feet come from? I notice there was one of those pole BMs so ubiquitous in the Goat Rocks (must have seen seven of them incl. one near the crack on Big Horn) about 15 feet lower than the summit rocks just north of the highest point. Perhaps this is the real 8184 point and the summit really is/still is 8201 ft."

Also, thanks for putting the pronunciation up there in the Overview. One small change: put it as "tie-it-un" instead of "tie-it-on." A small textual difference but a large one phonetically.
